You're just seeing one comment out of a person's day, how do you know someone pointing that out spends even five minutes a day thinking about AI? And anyway, many people come to social media and especially the fediverse with the intention of discussion the primary issues of our time, one of them being AI, and a style using wordart like this image probably became a highly upvoted post at least in part because of people being sick of AI flyers.

People "obsessed with AI" usually are concerned with the greater issues related to it, like the fascist tech-corpos taking over our government and economic systems, which is a hard thing to not agitate against when you are aware of what's going on.
